Abstract (en)
[origin: WO2016036927A1] An electrosurgical snare device is provided which uses a flow of inert gas to assist in the cutting and sealing process of tissue, while substantially reducing the fornnation of eschar and collateral tissue damage. The electrosurgical device includes a housing having a longitudinal axis; a support shaft attached to a distal end of the housing, and an end effector coupled to a distal end of the support shaft. The end effector includes a tube including a plurality of apertures and an electrically conducting spring disposed around the tube, where a spacing of the coils of the spring coincides with a spacing of the plurality of apertures, wherein a gas assisted electrosurgical effect is formed at each of the plurality of apertures when an inert gas flows through the tube and the spring is energized. The tube may be configured as a loop or snare.
